Onto the specifications, first of all it's worth pointing out that regardless of how good or fast the memory, controller or any other relevant bits used, SSDs with a capacity this small are never likely to match the theoretical performance maximum of their bigger cousins. This is because part of the speed advantage SSDs enjoy over traditional hard drives is due to their controllers allowing data to be recorded to all their flash modules simultaneously. In other words, one file can be divided into a large number of parts that can all be written at the same time. A smaller number of flash modules equals fewer parts, meaning you get lower overall performance.

However, though the Kingston 40GB's quoted read speed of 170MB/s is hardly surprising, a write speed of 40MB/s is shockingly bad! In fact, that's easily the worst quoted speed we've come across on a modern SSD. Consider, for example, that the even smaller 30GB version of OCZ's mainstream Agility (of which we reviewed the 120GB model only last week) quotes read and write speeds of 185 and 100MB/s, respectively.

So right now you might be thinking that the 40GB suffers these snail-like specifications thanks to a cheap, slow controller. In a rather more pleasant if no less controversial surprise this Kingston drive sports an Intel X25-M controller! In fact, this is essentially just a rebadged version of Intel's latest drives. As such, as well as full TRIM support (for an explanation of which we refer you to our Patriot TorqX review), it should provide blazing performance. At least it would, had Kingston not removed so many of the memory chips. Still, the proof of the SSD is in the testing, so let's get to it.

Thanks for the review. Very interesting.





I have a fairly nice Rig at home (i7 @3.6Ghz, 6 Gb RAM, GTX285 overclocked) that presently boots from the main 1.5TB Seagate drive and in the next few weeks I will be removing the RC of Windows 7 and installing a full version. This is a chance to slot in an SSD as I will be doing a complete re-install.





My question though is "is it worth it" ? I've never used an SSD before and I'm just wondering what difference it will make in the real world. If I ignore a slightly faster boot time (which I'd appreciate) would I actually notice any difference in the general performance of the PC ?





With only 40Gb I can't see that I'd be able to install much on the SSD apart from the OS and perhaps MS Office and a few small programmes (not big games). But if I buy a bigger SSD then your test show that most of them are massively more expensive, not that much bigger and often slower. So really it seems like this one or nothing (for now).





I'd be really interested in your thoughts.





Btw - I take it that Windows Swapfile is also located on the SSD ? How big do these things grow now-a-days and is the SSD the best place for it ?

AJ - have a look at the last paragraph in the article linked below, then read the rest of it if you are in any doubt about committing to an SSD.





This is the most recent in a series of highly informative articles about SSD development Anandtech has published in the last 18 months or so. All are worth reading if you are interested in the technology. I have just built an i5 system using an Intel X25M 160Gb, largely on the strength of them. Very fast!

The other TR's test of the 80GB version of this kit concluded that it wasn't worth it for a desktop: http://techreport.com/articles...

Thanks Guys. I thought the comments at the end of the 80Gb review especially relevant. Basically they thought even that was not big enough and in day-to-day use didn't really think it was worth it.





Seems SSD's are still more at home in a laptop.

40gb is more than enough for my system drive. I have win 7 pro 64, office, photoshop, and a host of other things and my c drive is at 27gb. You need a tool like treesize to see where the big folders are, and you can trim it by disabling hybernation and keeping your pagefile.sys in order.

Get 2 of these, RAID them, and compare them to the 64GB Agility?

@AJ:


Sorry for getting back to you so late, didn't check this review for comments in a while.





The simple answer to your question (if it's not already too late to be of use) is that it IS worth getting an SSD, as overall this should give you a more responsive system in the 'real world', and would appear to be the only thing that still really can make a difference to your high-end beast :)





40GB should be plenty for a Windows 7 install and a selection of most-used applications. The SSD is the best place for the Windows swap file (or PageFile), though with 6GB of RAM it's not likely to often be an issue either way. Ideally you should count on keeping double your memory size free for Windows to play with, but 28GB is still plenty for the OS and essential apps.





As to your point on SSD size relating to speed, in fact BIGGER drives tend to be FASTER - as long as they're using the same controller. Smaller SSDs, having fewer memory 'chunks' to write to simultaneously, will often be slower. Basically, get the best controller you can afford, and then the biggest size using that controller you can afford.

On page 2 you suggest this drive as full Trim support. It most certainly does not. Also, using acronis copies across the wrong partition alignment, so that might explain your slow write speeds. I'm surprised you don't mention alignment and offset here, it's a crucial issue. But I'm more surprised about the Trim assertion.

@John:


Just rereading this article and noticed your comment. You are correct in saying that this SSD does not OFFICIALLY support TRIM, but it was supposed to. Since it uses the exact same controller and memory as the Intel X25-M, there is no practical reason for it not to, but unfortunately Kingston was undercutting Intel on price, so Intel did not allow them to update their firmware with TRIM support - hence why the drive has now been discontinued.





However, there is apparently a way to activate TRIM support on this Kingston SSDNow V Series 40GB after all: http://www.overclock.net/ssd/6...
